The Electro-Harmonix POG2 effects pedal is a polyphonic octave generator that is incredibly versatile, offering anything from a slight extra jangle to an all-out impenetrable wall of symphonic sound. With the flexibility to adjust how many octaves up or down you'd like to go on the voice mix, plus an effects portion with attack, low-pass filter, detune, and the ability to save your favorite settings with one click, the POG2 knows no boundaries in the sonic landscape of your individual sound.
